July 21, 2009 – Cloud Computing with Hadoop, Map/Reduce and Cascading


Cloud Computing is one of the most popular and abused terms in technology today. Rather than trying to explain all the different meanings and abuses of the term, I will be presenting on a specific technology that most developers can understand and use today, Map/Reduce.

Made famous by Google as the solution to ‘how to index the Internet 6 times a day’, the map/reduce paradigm is applicable to a surprising number of business challenges in organizations of all types. I will be talking about the Apache solution, Hadoop ([]) and a very interesting abstraction layer on top of Hadoop, Cascading ([])

Building and Deploying 12 Factor Apps in Scala and Java

June 20, 2017

The twelve-factor app is a modern methodology for building software-as-a-service apps:

• Use declarative formats for setup automation, to minimise time and cost for new developers joining the project.

• Have a clean contract with the underlying operating system, offering maximum portability between execution environments.

• Are suitable for deployment on modern cloud platforms, obviating the need for servers and systems administration.

• Minimise divergence between development and production, enabling continuous deployment for maximum agility.

• And can scale up without significant changes to tooling, architecture, or development practices.

We will build a RESTful web service in Java and deploy the app to CloudFoundry. We will go over how to build a cloud manifest, how to keep our database credentials and application configuration outside of our code by using user-provided services and go over what it takes to build a 12 Factor application in the cloud. This presentation will be heavy on code and light on slides!
